        <h2 class="section-title">关于第4忆库</h2>
        <p>第4忆库是一个专门收藏和展示北京四中建校到如今校园记忆的数字化档案馆。我们致力于保存那些逐渐被时间冲淡的青春印记，让每一代四中人的故事得以延续。</p>
        
        <h2 class="section-title">为什么创建这个项目？</h2>
        <p>我们发现许多承载着集体记忆的校园物品——老校服、手写文稿、老证书、社团海报——正随着岁月流逝而消失。它们可能因为一次清理，搬家，或是简单的“觉得没用”，就彻底消失在了时光长河中。这些物件不仅是个人回忆，更是整个时代的文化象征。我们便建立数字档案馆，使得这些老物件得以永恒保存。</p>
        
        <div class="contribute-box">
            <h3>您是否保存着当年的校园物品？</h3>
            <p>无论是手写文件、校服、照片还是任何带有四中印记的物件，都欢迎与我们分享。我们将把它们存在档案馆中您永久保存这些记忆。</p>
